WebThe list of all divisors of an integer n will be calculated and returned in ascending order, including 1 and the number itself. For n>=1000 the list of prime factors of n will be used, … WebWhen necessary, a unit of the form {-1, 1}, {I, 1} or {-I, 1} is included in the list of factors. The last element in the list FactorInteger [n, k] gives what is left after the partial factorization. FactorInteger [n, Automatic] pulls out only factors that are easy to find. FactorInteger uses PrimeQ to determine whether factors are prime.

WebDivisors# How do you compute the sum of the divisors of an integer in Sage? Sage uses divisors(n) for the list of divisors of \(n\) , number_of_divisors(n) for the number of divisors of \(n\) and sigma(n,k) for the sum of the \(k\) -th powers of the divisors of \(n\) (so number_of_divisors(n) and sigma(n,0) are the same). Web20 jan. 2024 · For example, 7 is a prime, since it has exactly two whole number divisors, namely 1 and 7. On the other hand, 10 is not a prime, since it has four whole number divisors, namely, 1, 2, 5, and 10. The goal is for you to figure out more about how many divisors a number has. The concept of prime number may be useful in stating your …
